Arsenal secured their third straight win and third clean sheet in a row as they struck late to beat Southampton at the Emirates Stadium on Wednesday. That victory kept Arsenal in sixth place, 13 points off the top of the Barclays Premier League.

They owed this win to the latest goal from Alexis Sanchez, who netted his ninth league goal of the season and 14th in all competitions since arriving in north London in the summer.

It was particularly impressive, given Southampton's good defensive record. The goal was only the 10th they have conceded all season.

Meanwhile, Stoke City showed an improved performance at Manchester United, losing only 2-1 at Old Trafford after Steven N'Zonzi had equalised for the Potters. It was Stoke's third straight defeat, having lost at home to Burnley and at Liverpool.

It is the club's worst run since January 2014. If they lose to the Gunners, the four straight losses will represent the club's worst run since they lost a fourth game in a row in November 2011.

On the road, Arsenal have won only three games while drawing two and losing two. And their record at Stoke in the Barclays Premier League is poor, with just one win in six visits.

Their only win at Stoke came in February 2010; of their other five visits, the Gunners have lost three and drawn two. Last season, a Jonathan Walters penalty earned Stoke the three points.
